SM-G781B poor or no signal - FIXED IT

[wheelcorner78]

Hey,

i have a Samsung Galaxy S20 FE 5g which had poor or no signal for about two weeks now.
I checked signal strength in dBm and it was very poor and most of the time the phone was not enable to connect to a network.

Today i found this video. And this was the solution.
Somehow the connector from the antenna lost its contact to the motherboard.
After i reconnected it the phone had strong signal and a very good connection again.

Watch it. Probably it can help you too.

Also heard that the issue can be caused by CSC.
It is true?
For example if I have Malaysia (XME) CSC and I will change it to Canada (XAC) CSC - signal will be better in Canada, but not good in Malaysia?

From this I have question,
if I get Canada (XAC) firmware from SM-G781W and put it to my SM-G781B (Malaysia (XME) via Odin - I'll got a brick? or a nice working smartphone?

this is only in case you dropped the phone.

hello colleague

I totally agree with your problem.

It never gave me network signal problems.

but I opened my equipment to make an internal modification and the antenna was disconnected to my surprise.

the white antenna was the one that was disconnected.

and then I continued with my procedure.

my region was changed via SamFwTool and now signal is ok.
